to analyze postoperative complications and mortality, as well as evaluate the functional results of patients older than 95 years with a femoral neck fracture treated by cemented hip hemiarthroplasty. Material and method. Retrospective study of 33 cases, analyzing complications and mortality, identifying risk factors, and evaluating cognitive status, functionality and level of ambulation after surgery. Results. eight patients (24,2%) presented postsurgical medical complications, finding blood transfusion and bilateral hemiarthroplasty as predictive factors, and 11 died in the first year (33,3%), finding the previous functional status and the taking of antiaggregants or anti-coagulants as risk factors. All worsened functionally after the fracture. Conclusions. we consider fundamental, in order to optimize the treatment, the precise preoperative evaluation of the patient given the limited life expectancy and the high mortality rate in the first year after hip surgery.
